Objective To observe the clinical effect of Xingnaojing injection combined with naloxone in the treatment of hypoxic ischemic encephalopathy.Methods 62 patients with hypoxia ischemia encephalopathy were randomly assigned into the control group(31 cases)and the treatment group(31 cases).The control group used naloxone treatment on the basis of the conventional treatment.The treatment group received Xingnaojing injection combined with naloxone treatment on the basis of routine treatment.The changes in different time of Glasgow Coma Scale(GCS) scores of the two groups after treatment were compared.Results After treatment for 1 ,5,1 0,1 5d,the GCS scores in the control group were (5.27 ±0.87)points,(9.03 ±0.72)points,(1 0.03 ±0.72)points,(1 3.03 ±0.72)points respectively,which in the treatment group were (5.1 4 ±1 .03)points,(9.24 ±1 .06)points,(1 3.31 ±2.83)points, (15.31 ±0.93)points.The differences of GCS scores after treatment for 15,10d between the two groups were statistically significant(t =1 5.1 1 3,1 0.501 ,P =0.00,0.00).In the control group,the total effective rate was 50.0%,which of the treatment group was 82.7%,the total effective rate between the two groups had statistically significant difference (χ2 =6.437,P <0.05).Conclusion On the basis of routine treatment,Xingnaojing injection combined with naloxone in the treatment of hypoxic ischemic encephalopathy has better effect than the single use of naloxone treatment.
